Product Description

The V-type ball valve is a fixed ball valve and a single-seat valve. The adjustment performance is the best in the valve. The flow characteristics are equal percentages, and the adjustable ratio is up to 100:1. Its V-shaped slit has shearing action with the metal seat, especially suitable for media containing fibers, tiny solid particles, slurry.


The valve is suitable for frequent operation, quick opening and closing, light weight, small fluid resistance, simple structure, small relative volume, light weight, easy maintenance, good sealing performance, no restrictions on the installation direction, the flow direction of the medium can be arbitrary, no vibration, The noise is small.

Main components

1. One-piece valve body

The V-type control ball valve uses a one-piece valve body to prevent separate flange leakage.

2. Bearing

The V-shaped ball adapts the upper and lower rods to the bearing. The bearings are made of composite materials with good lubricity, high wear resistance, high mechanical stability and low opening torque, ensuring excellent sensitivity and sensor speed.

3. Movable seat

The valve adopts a movable seat structure loaded with a Belleville washer or a column spring. The spring seat has the best contact between the valve seat and the disc, and has good sealing performance. PTFE seats and metal seats are available to meet different application requirements.

4. V segment ball

Specially designed V-balls have the same percentage flow characteristics, high precision control performance, and powerful cutting and self-cleaning features.

5. Spline connection between shaft and ball (for 10" and above)

The ball and shaft are connected by splines. It provides a seamless matching ball that prevents the shaft from having enhanced control accuracy.

6. Low capacity

For ultra low flow applications, the DN25 offers low volume valves for precise control.

7. ISO5211 direct mounting mat

The valve has an ISO5211 direct mounting mat. It can be easily connected to a variety of drives, such as handles, worm gears, pneumatic actuators, electric actuators, hydraulic actuators and more.

8. Full silica sol investment casting body

The main body of the valve is fully silica sol investment casting, so the surface is very smooth and more beautiful.


In services of petroleum, chemical industry, pharmaceutical, waste water disposing and tank trunk. It's used for on-off and regulating various mediums, such as liquid, gas and slurry, ideal for high viscosity and fibre and grain containing medium.
